The
EMES QUARTZ is the big version of the KOBALT Nearfield monitor. The
second of a new generation 2 way bi-amplified near field Monitor,
specially designed to meet the best performance at a reasonable price
point.
Well known EMES HR line features are found in the QUARTZ plus added
features like:
The BI-Port and the ISO-Rails
The BI-Port was specially designed to keep the cabinet dimensions
as small as possible, while supporting the High frequency section.
Therefore we integrate the 25mm Neodymium Tweeter In the Center of
the BI-Port (Bass Reflex System) for two reasons; To aim for
an efficient Air cooling of the "little tweeter" by the
Woofers Air flow, secondly and most important to generate a "velocity
field (ring shape)" around the Tweeter to support it's High frequency
dispersion pattern over long distance!(riding on along wave) Result
- an unbelievable precise Stereo-Image over distance.
Also the ISO-Rails are features which have practical aspects
as well as acoustical once!
Most available cabinets have flat sheet surfaces, such speakers have
hard times to stick on the location they were placed on, especially
when they are pushed hard, manually or by the moving force of the
Woofer!
Not such strange things happen to the KOBALTs! The cabinet is standing
on the ISO-Rails - a special silicon profile - only. So there
is no coupling to surface underneath nor is any "slip" behaviour
going on, so the low end is always tight at any time!
As always at EMES, matched high quality drivers
are chosen, because to us they are the most critical part in a quality
Studio Monitor System!
The Low range (59 - 2000Hz) is reproduced by a
17cm polypropylene Membrane HDS-driver. A 25mm high efficiency
Neodymium Tweeter located in the BI-Port is used from 2
- 20 kHz!
We at EMES always use identical amplifiers, to have the lowest
time related distortion possible! Therefore 2 identical build
in 80W rms amplifiers which deliver a powerful and optimized output
drive a single QUARTZ Monitor. This is one of the many design
criteria's to the EMES audio performance.
To adjust the monitor to your personal listening level, a 16 position
dip-switch has been added! This allows to control the midrange
performance as wel as to adjust the listening level!
We ship the QUARTZ as all other EMES monitors
as matched pairs!
